Flange-Lubricating Device, of which` the foll lowing is a specilication.

This invention relates to a device for prolonging the effective service or life of flanged wheels of rail road rolling stock.

' One of the sources of wear and deterioration of flanged wheels is the friction between the flange and the side of the track. Indeed the expense of renewal and repair due to this source alone forms a large percentage of the total repair and renewal of the wheels, for it frequently occurs in practice, that Wheels otherwise good must be removed, machined, and reset, involving considerable expense not alone from the actual cost of repairs,.but the incidental loss due to the removal from service of the locomotive or other stock, which otherwise may be in good repair.

The object of the invention is to provide means for applying lubricant, locally tothe wearing surface of the iianges of rolling stock and especially to` those of the locomotive. This object is accomplished by means of devices illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of a detail `of the lubricating shoe on a large scale. Fig. 2 is a transverse section of Fig.. 1. Fig. 3 is an elevation of one form of my device on a smaller scale than the foregoing figures. Fig. 4 shows a side view of my device in position as applied to a locomotive.

Referring now to the drawings for a fuller description of this invention, l indicates a shoe or chambered receptacle. conforming in shape to the flange of a wheel, being formed as an inverted Y or saddle in transverse section, so as to straddle a small arc ofthe flange. It is provided with a chamber or 'recess 2 on the inner side of one of the arms of thel Y. or saddle. The portion of the saddle forming the side walls of the recess 2 is shaped to conform. apoximately .to the contour of the flange. the recess is provided a packing or swab 3 of preferably absorbent material.

Extending radially froni= this saddle like shoe is an adjustable connection, shown in the drawings as consisting of a sleeve 4 loosely fitting and movable upon a suitable bar 5, which adapted to be attached by bolts or other mutable devices to any convenient part car etc. a s ring 6 is provided to effect a downward resi ient pressure upon the shoe to maintain thesame in proper relation with the flange of the wheel, one end of the spring 6 bearing against a collar a on the bar 5, and the other end of the spring engaging the upper end of 'the sleeve 4. The bar 5 which 1s provided with a passage b extending therethrough to of the frame or structure of the locomotive,

Between the. bar 5 and the sleeve 4- conduct lubricant to the interior of the shoe motive, car etc., but where a number of these devices are used, as for example on'the various wheels of a locomotive or train, as 'illustrated in Fig. 4 of the drawings, the bars 5 leading through the shoe are connected by a pipe or pipes 11 to a main supply pipe 8" leading to a lubricant receptacle 7 suitably mounted on the frame of the locomotive or car. Pipe 8 is rovided with a valve 9 to control the supp y of lubricant to the shoes, said valve havin an operating handle ex tending to the ca. y

A pressure pipe 12 connects the boiler or other source of pressurewith a receptacle 7 and a Ivalve '13 is provided suitably situated to control the admission of, pressure to the lubricant.

ln the arran ement illustrated in Fig. 3 an additional'con uit for the lubricant to the interior'of the shoe is rovided by a pipe 8 connecting the rece tac e 7 and the shoe, and said pipe is provide with a valve 9 and with a lower flexible portion O to accommodate for the vertical playof the shoe. l

In practice the swab or filling of the chamber 2 is kept supplied by the manner shown or other suitable means, with a heavy lubricant, and by its loose contact transfers a ortion of this lubricant to the wearing s ace of the flange and consequently to the portion of the rail in contact therewith. At curves or. other places of exceptional friction pressure maybe admitted to the oil receptacle so as to force an increased supply of oil onto the flange or. track, at the discretion and control of the engineer.

, Having thus described this invention what l claim is. 1. In a lanve lubricating device a shoe supported close y adjacent the face of a flange and having a chamber for lubricant, said chamber having a delivery outlet arranged ics c face o wie ^ itheange and ofla size and shape Spending to a portion of vthe face of' the E a ange lubricating device, a shoe )ported closely adjacent the face of a iiange d havingv a chamber for lubricant, said l.; amberfhaving a delivery outlet arranged adjacent the -ange andof a size` and shape corresponding" to a portion of'the Wearing the iiange. 3. In a flange lubricating device, vthe combination cfa shoe or receptacle for lubricant', means comprising a `Y or saddle shaped 'sec- .tionv for effecting the loose contact1=ofthe lubricating shoe surface with the wearing sun' yfaceof the flange, resilient-means for holding the devicein Working relationship tothe flange and means to apply lubricant to the flange,areceptacle or retainer for lubricantL communicating Withthe shoe'and means for applying -pressure to the lubricant therein.. 4. In adiange lubricating device, a shoe ,yieldably supported closely adjacent the face of a iiange and having a chamber for lubri- 'cantjsaid chamber. having a delivery outlet arranged adjacent the iange and of a size and sha e corresponding to a portion .of the face of t e, flange.

5.f in a iange lubricating device, 'a shoe supported. closely adjacent the face vof -a.

ange and having a chamber for lubricant,l

'said chamber having a. delivery outlet arranged adjacent the flange and of a size and shape corresponding to a portion ofthe face of the lange `and absorbent material in the chamber. Y

.-6. in a ange lubricating dev-ice, a shoev shal ed to 'straddie a iange and provided with a chamber for lubricant said chamber being .provided with a delivery. orifice arranged adjacent to and corresponding in sizer and shape to a .portion ange.V

7. In a flange lubricating device the combination of a shoe or receptacle formed of Y of the surface of the adjacent the ian'ge and-of-.a.size and shape corresponding f to'i alportionoi theface oi flange, a conduitftojcarry lubricant from the supply container to the chamber ofthe shoe .or saddle section to straddle the ange, there being a pocket or chamber in one o f the arms of the Y, and a swab or vabsorbent material in the pocket adapted to ap ly a lubricant to the wearing surface oit-he gauge.

chamber. having. a delivery .oriiice arranged and having, a sliding .connection with the shoe, and a 'spring to maintain the shoe in Working relationship tothe flange.

9. In a iiangelubricating'device, a supply containerfor lubricant,'a shoe to be supportedclosely adjacent the face of the iange and having a chamber for lubricant, said chamber having a delive vorifice arranged adjacent the iiange and .o asize and shape corresponding to a portion of the face of the iiange, a conduit to carry'lubricant from the '70 supply container to the chamber of the shoe, and means for applying pressure to the lubricant in the supply container'.A
